💸 Introduction
You’ve probably seen ads for “loft conversions from £25,000” — and while that may seem appealing, it’s rarely the full story.
At MS Loft Conversion, we often meet homeowners who are surprised by hidden costs or unrealistic quotes from less experienced builders.
This post breaks down the real costs behind a loft conversion in Kingston, what affects your budget, and how to avoid financial surprises.
🧱 1. The Type of Loft Conversion Matters
Not all loft conversions cost the same. Here’s a quick cost comparison (2025 estimates):
Type Approx. Cost Range
Velux £25,000–£30,000
Dormer £35,000–£50,000
Mansard £50,000–£70,000
Hip-to-Gable £45,000–£60,000
A dormer conversion in Kingston may cost more than average if your roof structure is complex or access is tricky.
🏠 2. Planning & Structural Costs
Unexpected costs can come from:
Structural reinforcements
Steel beams
Building control compliance
Party wall agreements
Planning permissions or applications
That’s why we do a full structural assessment up front—so there are no surprises later.
💡 3. Design Choices = Price Changes
Custom finishes, skylights, en-suite bathrooms, built-in storage—these all add cost, but also value.
At MS Loft Conversion, we help you design within your budget without compromising on quality.
🛑 4. Beware of Unrealistic Quotes
If a quote looks too good to be true, it usually is. Cheaper prices often mean:
Inexperienced tradespeople
Sub-par materials
No insurance or guarantees
Surprise “extras” mid-project
We provide transparent pricing, local references, and full project breakdowns.
💬 Conclusion
A loft conversion is an investment—but with the right planning and the right builder, it doesn’t have to break the bank.
MS Loft Conversion offers affordable, honest pricing for bespoke loft conversions across Kingston and surrounding areas.
